Bosellia mimetica in the Bahamas

February 3, 2002
From: Colin Redfern

Dear Bill,
I see that Bosellia mimetica is already on your Species List, but I thought you might like to have photos of two additional specimens. These are both from Abaco, Bahamas, where B. mimetica is occasionally found close to shore on Halimeda opuntia or on small rocks. As shown by these photos, the animal's shape can change considerably when in forward motion, and the shade of green is quite variable. The photographed 9 mm animal is the largest I've seen, but Clark (1984) recorded a 15 mm specimen from Bermuda.

UPPER: Two photos of a 9 mm specimen. On the underside of a rock in 0.3 m, shoreline 1 mile SE of Cooperstown, Abaco, Bahamas. June 12, 1995.
LOWER: Three photos of a 5 mm specimen. On Halimeda opuntia in 0.6 m at entrance to lagoon on No Name Cay, Abaco, Bahamas. June 30, 1995.

• Clark, K. B. 1984. New records and synonymies of Bermuda opisthobranchs (Gastropoda). The Nautilus, 98(2):85-97.

Dear Colin,
Thanks for the further information. I remember spending many hours searching for Bosellia in the Indo-Pacific, because as I mentiond in an earlier message Eveline Marcus was very keen to see specimens from the Indo-Pacific - but they don't seem to exist here.
Best wishes,
Bill Rudman
